Timsa Sutta: Thirty
translated from the Pali by

Now on that occasion the Blessed One was dwelling in Rajagaha, in
the Bamboo Grove. Then thirty monks from Pava — all wilderness
dwellers, all alms-goers, all triple-robe wearers, all still with
fetters — went to the Blessed One and, on arrival, having bowed
down to him, sat to one side.
Then the thought occurred to the Blessed One, "These thirty monks
from Pava... are all still with fetters. What if I were to teach
them the Dhamma in such a way that in this very sitting their
minds, through lack of clinging, would be released from
fermentations?"
So he addressed the monks: "Monks."
"Yes, lord," the monks responded.
The Blessed One said, "From an inconceivable beginning comes
transmigration. A beginning point is not evident, though beings
hindered by ignorance and fettered by craving are transmigrating
& wandering on. What do you think, monks? Which is greater, the
blood you have shed from having your heads cut off while
transmigrating & wandering this long, long time, or the water
in the four great oceans?"
"As we understand the Dhamma taught to us by the Blessed One, this
is the greater: the blood we have shed from having our heads cut
off while transmigrating & wandering this long, long time, not
the water in the four great oceans."
"Excellent, monks. Excellent. It is excellent that you thus
understand the Dhamma taught by me.
"This is the greater: the blood you have shed from having your
heads cut off while transmigrating & wandering this long, long
time, not the water in the four great oceans.
"The blood you have shed when, being cows, you had your cow-heads
cut off: Long has this been greater than the water in the four
great oceans.
"The blood you have shed when, being water buffaloes, you had your
water buffalo-heads cut off... when, being rams, you had your
ram-heads cut off... when, being goats, you had your goat-heads cut
off... when, being deer, you had your deer-heads cut off... when,
being chickens, you had your chicken-heads cut off... when, being
pigs, you had your pig-heads cut off: Long has this been greater
than the water in the four great oceans.
"The blood you have shed when, arrested as thieves plundering
villages, you had your heads cut off... when, arrested as highway
thieves, you had your heads cut off... when, arrested as
adulterers, you had your heads cut off: Long has this been greater
than the water in the four great oceans.
"Why is that? From an inconceivable beginning comes transmigration.
A beginning point is not evident, though beings hindered by
ignorance and fettered by craving are transmigrating &
wandering on. Long have you thus experienced stress, experienced
pain, experienced loss, swelling the cemeteries — enough to become
disenchanted with all fabrications, enough to become dispassionate,
enough to be released."
That is what the Blessed One said. Gratified, the monks delighted
in the Blessed One's words. And while this explanation was being
given, the minds of the thirty monks from Pava — through lack of
clinging — were released from fermentations.
